Why do planets not twinkle?
John AlexanderThe twinkling is not from the stars but is due to disturbances in the air.
Stars are too far away, so we can not see the disk of the star. What we get instead is the point source of light... planets are near bye comparison to stars and we actually see their disk or body. The light beam bends in the atmospheric hot air layers, but the planet's image is larger and can create good image.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
